Miss Blythe, 45, from Worthing in Sussex, has been rallying fellow protesters through a group on Facebook she set up called The Witch is Dead, which has more than 5,000 members and calls for “demonstrations of disapproval” across the country.

Since being exposed on Wednesday by The Telegraph as an architect of the “celebrations”, she has appeared to revel in the "15 minutes” of fame.

She wrote this morning: “The more publicity the bigger the party!”

Miss Blythe, who says she now works as a “workshop facilitator”, claimed she was not complaining about the press coverage.

"It gets the word out which is in fact the point: to draw attention to important political issues!”

She said of an image of her in fancy dress: "Still, I look good in a corset... I know I make Katie Price look like a saint!”

She received plaudits from friends. But some of her former neighbours in Dalmeny Road, North London, said she was a "noisy" campaigner who fell out with local residents.

One neighbour, who did not want to be named, said: "She was a nuisance. As a neighbour she was awful. If things weren't going her way she would just switch. She would talk about Palestine. She was just a horrible, horrible person."

A number of places on Miss Blythe's list of planned demonstrations saw disorder and protests on Monday, including Bristol City Centre and George Square in Glasgow.

Miss Blythe, a University of East London graduate, has worked with a workshop company that visits secondary schools.

She specialises in “facilitating workshops for young, excluded and potentially criminalised individuals and uses drama techniques she has developed to explore resolution of conflict and oppression”, according to the company’s website.

She claimed she had invited more than 5,300 people to a “flash party” to mark Lady Thatcher’s passing, with the message: “Anyone else like to join us?”

The Facebook page reads: “Come and celebrate our liberty and freedom from tyranny! On the day Maggie stands down, once and for all!”

She appears in photographs posing alongside Tony Benn, the former cabinet minister, and Owen Jones, the Left-wing writer.

Speaking to The Telegraph, Miss Blythe said her dislike of the former prime minister came from being told she might never find work on leaving school in 1984.

She said her father was a “Leftie”, while her mother voted for Lady Thatcher. She describes herself as a Labour supporter, but hopes it will return to being a party of the people before she votes Labour again.

Miss Blythe said the parties would be targeted at Lady Thatcher’s policies and did not intend to “gloat” at her passing. It’s not about gloating and being mean. It’s about using that date to reflect on the past, however unfortunate that day may be for some people,” she said.

“She has family and they will grieve. She’s not the enemy right now; her legacy is the enemy.

“I’m calling for a peaceful demonstration of disapproval and letting the Government know we’re not stupid and we haven’t been brainwashed by more prosperous times since then.”

She described the protests as a “group catharsis”, for “survivors of the Thatcher years” and likened them to sufferers of post traumatic stress disorder.

She added: "She was a despot. They danced in the streets when Hitler died too.”

Anarchist groups have warned of more mass protests on Saturday, with 2,000 to 3,000 people expected to attend.

The events, at 25 locations across the country, are being organised by a group called Class War, with the help of other organisations such as the All London Anarchist Revolutionary Mob, which says it is “committed to radical action to undermine the state”.
